For the problems 29-32, use () 5 6 fx x =+ and 2 () gx x x =+ .

Answer:

32.50

Step-by-step explanation:

It is simple. You need to know the basics of money, fractions, and well... Math! :)

if you take 13 and multiply it by 2 you get 26

Take the 26 and put it aside ------------->         26

divide 13 in half. that would be 6.50

6.50 + 6.50 = 13      

Now get the 26 -------------------------->  26

and add 6.50 to 26.

That would be 32.50!

Answer:

[tex]c = 63\\b=21[/tex]

Step-by-step explanation:

Let number of pounds of cans collected by Amy = [tex]a[/tex]

Let number of pounds of cans collected by Bruce = [tex]b[/tex]

Let number of pounds of cans collected by Carlos = [tex]c[/tex]

As per question statement, total number of cans collected = 168

[tex]a+b+c=168[/tex] ..... (1)

Number of pounds collected by Bruce is [tex]\frac{1}{3}[/tex]rd of the pounds of cans collected by Carlos.

[tex]b = \dfrac{1}{3}c ..... (2)[/tex]

Number of pounds collected by Amy is equal to number of pounds collected by Bruce and Carlos combined.

[tex]a = b+c[/tex]

Using equation (2):

[tex]a = \dfrac{1}{3}c +c \\\Rightarrow a =\dfrac{4}{3}c ..... (3)[/tex]

Using equations (2) and (3) in equation (1), we get:

[tex]\dfrac{4}{3}c+\dfrac{1}{3}c+c =168\\\Rightarrow \dfrac{8}{3}c = 168\\\Rightarrow c =63[/tex]

Using equation (2):

[tex]b = \dfrac{63}{3} = 21[/tex]

Answer: 7

Step-by-step explanation:

Answer: chemical decomposition produced by passing an electric current through a liquid or solution containing ions. In chemistry and manufacturing, electrolysis is a technique that uses direct electric current to drive an otherwise non-spontaneous chemical reaction. Electrolysis is commercially important as a stage in the separation of elements from naturally occurring sources such as ores using an electrolytic cell. Electrolysis is used in industry for the production of many metals and non-metals (e.g., aluminium, magnesium, chlorine, and fluorine). Electrolysis is commonly employed for coating one metal with another. The method of coating one metal with another using an electric current is called electroplating.

The required simplified expression of the given expression 10x -(-7+6x) is 4x - 7.

The process in mathematics to operate and interpret the function to make the function or expression simple or more understandable is called simplifying and the process is called simplification.

Here,
To simplify the expression 10x -(-7+6x), we can apply the distributive property of multiplication over addition and simplify the expression inside the brackets first.

-(-7+6x) = -1×(-7) + (-1)×6x
          = 7 - 6x

Substituting this result into the original expression gives:

10x -(-7+6x) = 10x + 7 - 6x

Now we can combine like terms by adding the x terms and the constant terms separately:

= (10x - 6x) + 7

= 4x - 7

Therefore, 10x -(-7+6x) simplifies to 4x - 7.

Answer:

A. y = 7x + 2

C. y = 2 - ⁷/3x

D. y - 2 = 4x

Step-by-step explanation:

The equation of any line that would intersect the orange line at the y-intercept, 2, would have the same y-intercept value of 2.

Thus, from the options given, the following equations has y-intercept (b) of 2.

A. y = 7x + 2

C. y = 2 - ⁷/3x

D. y - 2 = 4x

All three equations have a y-intercept value, b, of 2.

Note: option D, y - 2 = 4x, can be rewritten as y = 4x + 2.

Answer: A/C/D

Step-by-step explanation: A. y = 7x + 2

C. y = 2 - ⁷/3x

D. y - 2 = 4x

Answer:

Step-by-step explanation:

use the formula

tanФ⁻¹ = y/x

where y = 3

           x = 9

plugin values into the formula:

tanФ⁻¹ = y/x

           = 3/9

tanФ⁻¹ = 0.3

     Ф = inv. tan 0.3

     Ф = 18.4°

therefore, the angle D = 18.4°

Step-by-step explanation:

An equiangular triangle is a triangle with three congruent interior angles. The angles of any triangle add up to 180 degrees. With three angles in a triangle that are all equal, this means each angle is 60 degrees (because 180 divided by 3 is 60).

An Acute triangle is a triangle with all of its angles being something less than 90 degrees. Since an equiangular triangle's angles all measure as 60 degrees, then the statement in the question is always true.

Given:

The equation is

[tex]y=-1(x-4.5)^2+15.25[/tex]

To find:

The standard form of the given equation.

Solution:

We have,

[tex]y=-1(x-4.5)^2+15.25[/tex]

It is a quadratic equation.

The standard form of a quadratic equation is [tex]y=ax^2+bx+c[/tex]. So, we need to write the given equation in this form.

[tex]y=-(x-4.5)^2+15.25[/tex]

[tex]y=-[x^2-2(x)(4.5)+(-4.5)^2]+15.25[/tex]         [tex][\because (a-b)^2=a^2-2ab+b^2][/tex]

[tex]y=-[x^2-9x+20.25]+15.25[/tex]

[tex]y=-x^2+9x-20.25+15.25[/tex]

[tex]y=-x^2+9x-5[/tex]

Therefore, the required equation in standard form is [tex]y=-x^2+9x-5[/tex].
